Revision A | G5 1.8GHz | 20-inch

Nine months had passed since the introduction of the gargantuan 20-inch Flat Panel iMac. It turns out that the 20-incher was both a beginning and an end. It was the first 20-inch iMac ever and the last model of the sunflower design.

The beautiful “floating” display design had ruled the iMac world for two years, seven months and 24 days. It was time for a change and the Apple design team outdid itself once again with the introduction of another stunning concept — the iMac G5.

At first glance, the entire computer might be mistaken for a stand-alone LCD display. At only 2-inches thick and encapsulated in clear crystal, the entire computer was flattened and tucked away behind the display in a gorgeously-compact design.

This svelte beauty was suspended on a brushed aluminum stand that was hinged to allow for tilt adjustment. It was also VESA-compliant and could be mounted on a wall.

While not the first all-in-one design of this type, the iMac G5 certainly stands head-and-shoulders above competing designs and is a paragon of simplicity in comparison.

A new design naturally deserves a new processor. This model was powered by the 1.8GHz PowerPC G5 processor with “Velocity Engine.” It had a 512K on-chip L2 cache running at full processor speed and a 600MHz frontside bus. The hard drive capacity was 160GB, double that of its siblings.

This is the high-end model. Both it and the 17-inch 1.8GHz iMac were outfitted with SuperDrives. The base model was a 17-inch 1.6GHz iMac and had a slot loading Combo drive instead. The optical drive was located near the top of the right side and loaded vertically.

Apple was skimpy with the memory again. This model had 256MB PC3200 DDR SDRAM but was rated 400MHz, and for the first time, expandable to a total of 2GB.

All three models in this series had the NVIDIA GeForce FX 5200 Ultra graphics processor with AGP 8X support, including 64MB of dedicated DDR video memory.

The entire lineup had two FireWire 400 ports, three USB 2.0 ports, (two more USB 1.1 ports on the keyboard), VGA output port, S-video and composite video output, headphone output, audio line in, and built-in modem and Ethernet.

It came AirPort Extreme ready with a build-to-order option for an internal Bluetooth module. Matching white Apple keyboard and mouse were standard or customers could opt for wireless versions for an added price. The speakers were now built-in.

All this and only 25.2 pounds (11.4 kg).
